    A 5k top of the line retina display, being powered by a... mid-range laptop GPU? :(

    I'll reserve judgment till I can see it in action
    At this point, nobody can say anything for sure

    Definitely would be waiting to see what real world use is like.

    Think you have to upgrade to M295X for any video work.

    Still a good price when Dell 5K monitor alone is expected to be around $2,500.

    Well there goes my money; I'll stick with my existing iMac thanks.

    No one is going to buy this iMac except the uninformed and stupid.

    Apple going with this GPU with this display is the biggest mistake they've ever made.

    Consider me uninformed and stupid. Ordered one. Looks like I can use my 32GB RAM from my late 2012 iMac. Sweet!

    27-inch iMac with Retina 5K display

    With the following configuration:

    • 4.0GHz Quad-core Intel Core i7, Turbo Boost up to 4.4GHz
    • 8GB 1600MHz DDR3 SDRAM - 2x4GB
    • 1TB Fusion Drive
    • AMD Radeon R9 M295X 4GB GDDR5
    • Apple Magic Mouse
    • Apple Wireless Keyboard (English) & User's Guide
    • Accessory Kit

    Also does Apple's custom display chip impact response time of the display in anyway? Any buyers who plan to do some gaming should hold fire until we know more.

    maybe not on desktop apps, but in stuff that relies heavily on full screen and that gpu, then it might. especially gaming that will utilize such high resolutions.

    cannot agree more
    its total dissaster
    at least for me
    i had such a great expectation thinking it will get nvidia 980m(which is a perfect fit and first mobile chip that is as powerful as desktop)
    why apple why ?????? [​IMG]

    Yep, count me out as well. What a waste not to drive it with the 980m.

    I think this was done on purpose not only to keep costs down like someone else said but perhaps to encourage an upgrade for a powerful graphic card next year.

    A bit similar what the MBPR went through. It will take a year maybe even two to crush the lag. Because there will be, especially with games. No way any game modern game will run above 15 fps at full 5k.

    I couldn't agree more, a 980M would have made the perfect iMac in every respect, an absolute classic machine which would have been regarded as a benchmark for the iMac hierachy.

    i guess money talks louder than sanity at Apple Towers...

    Unless I'm missing something, can the eye even really see 5k?

    See this type of complaint over on the Notebookreview forums all the time.. Don't look at 5k res and think you're forced to run your game at 5k.. That's not even going to happen with a TOP OF THE LINE DESKTOP GPU.

    You're going to down-res your games to 1080p, 1440p.. Whatever sounds reasonable. I haven't done the math but maybe there's a 1:1 pixel scaling resolution you can use so that there's no weird pixel interpolation..

    With 4k, if you switch to 1080p, it's 1:1 pixels (4x4 pixel blocks = 1:1 ratio)..

    I don't know what res (and let's hope there is) one that will make it look like a native 1:1 with lower resolution just for the sake of gaming.

    ----------

    Yes? 5k resolution spread out across a 27" panel you could probably still see pixels if you get close enough.

    ----------

    M295X should as fast or faster than the 980M.

    ----------

    Also, is everybody missing the fact the base graphics card is pretty much same performance as last model's 780M? Do some research before assuming what is slow and what's not? C'mon.

    780m vs m298x

    Does anybody have any idea about which card are strongest, i do a lot lot photoshopping and some gaming, and i saw a test of some games on the 680M, and all the games ran perfect in 2560* but will the M295X be able to do the same. ??

    The Radeon M295X 4GB is the unreleased full Tonga XT chip. The cutdown version of Tonga is the desktop Radeon HD 285.

    dude its not even close to it
    290x is less powerful then 780m(which we have on current gen)
    so 295x will be same or a very little bit more but not even close to 980m

    No way will it be as fast as the 980m, more like around the performance of the 880m, which in itself is more or less the same as the existing 780m in the non retina 27".

    Yes. If you plan on playing games at the native resolution, prepare for a slideshow. For standard day to day desktop usage, I think you'll be fine with the m290x.

    If you think that m290x is a mid-range laptop GPU, then I don't really know what to say... :D This is one of the fastest laptop GPUs available in 2014. And if my integrated HD4000 is effortlessly able to draw a 3840x2400 desktop, I doubt that the m290x would have much trouble with 5120x2880

    Don't get me wrong, I am quite surprised why Apple didn't go with the Nvidia Maxwell... time will tell, I guess.

    you might want to read this before saying anything
    especially this part "he M290X performs a bit below the GeForce GTX 780M and slightly above the Nvidia GeForce GTX 680M."

    And you know this how? We're both speculating after all.. There's no benches out on the M295X this far but I am going to bet it's parallel with a 980m.

    ----------

    Spectulation is what we're both doing, see my post above.

    ----------

    It doesn't matter, the point is that the BASE graphics almost same as top tier graphics from last model.
